DF ROBOT MiniQ II User manual

1. Get to Know your Robot
1．Key Points
You will learn：
*Recognize every component of the car
*How to use Arduino IDE and finish some preparation work
Equipment needed：
*MiniQ II （with batteries）
*USB cable
2．Introduction
First of all，congratulations to you for getting such an attractive robot. This is an interesting
and fully functioning robot，at the same time, it also can help you learn Arduino well. You can
realize your idea like hunting the light or transport drink and orientation recognition and so on.
Now, let’s have a look at our robot：
1) Front view of MiniQ II

2) LEDs on the bottom of MiniQ II
Components on the car：
3) Components and their locations

4) The front view of the robot
Function about every component：
1. Infrared transmitter：transmit the infrared signal, the signal can be used for detecting
obstacles
2. Photosensitive diode：sensitive with the light, so it can help you get some information
about the light
3. Infrared receiver：receive infrared signal, the signal can be used for obstacle avoidance
4. Button：can be programmed for your idea
5. RGB LED：you can change its color use your code, it can show as an alarm and other
things you want
6. USB port：download your code and let your robot talk to your computer
7. Buzzer（passive）：be an alarm bell or sing a simple song
8. Controller：runs your code
9. Motor：can be controlled to run forward or backward, so that the car can turn left or right
freely
10. Reset button；Reset the robot, the program in the robot will runs again from its initiation
11. Power switch：power switch of the robot
12. Power port：power provided from this port
13. Charge port: if your batteries can be charged，you can charge them from this port thus
they can be hold in the car
14. Infrared line-follow sensor: can be used for detecting for white or black lines
3.Download your first program
Program controls every step of your robot. So you must know how to download your
program into your robot. And firstly, you need to download the software, this is the link：
ArduinoIDE.
Open the website:http://arduino.cc/en/Main/Software, you will see：
Line tracking sensor

5) Download page
You should download the right version to fit your system of your computer, take
windows for example：if you finish the download and open the software, you will see：
6) ArduinoIDE
OK，connect miniQ to your computer，

7) Connect to your computer
Press the power button，you will see the leds on the bottom of the MiniQ will be ligthed,
this shows that the robot gets power successfully
Next step，install the driver. Open the device manager:Right click my
ComputerPropertiesDevice Manger
8) Open device manager
You will see：

9) Unknow device
It shows we need to install its driver, you can install it by windows itself but it is faster do it
yourself, right click Arduino LeonardoBrowse my computer for driver
softwareC:\arduino-1.0.4-windows\arduino-1.0.4\driversNext，you will finish the installing.
10) Install the driver

After the action above, open theArduino IDE, you will see:
11) Arduino Serial Port
Click “Tools”“Board”to choose”Leonardo”, and “Tools””Serial Port” to choose the
port.
Now，open the file“ObstacleAvoidance.ino”,
12) You need to open this folder

13) Program has bee opened
Click the upload button and wait for the the message below.

14) Program upload
Well, take off the USB cable, put your robot on the ground and see what will happen, it avoid the
obstalce itself, doesn’t it?
